This multi-pack of Replacement Mini Bands works with the Vice Grip Trainer and includes four pairs of color-coded resistance bands. Measuring 12", they double as fit-loop bands for lower-body movements like squats and hip thrusts and are great for rehab, physical therapy, and mobility work. Color-coded by load — Red (light), Black (medium), Purple (strong), Green (ultra) — and made from durable, non-slip latex that holds its elasticity over time.
